Lil, at the moment there are Mousserons everywhere her (I'm in the SW too).
Look out for "fairy rings" like this :
Check though before eating any of them. You can take them to the pharmacy, they'll check them for free.
They're good cooked with parsley and a bit of garlic.
It's also the season for Morels which are rarer but really delicious !
You
should also be able to find Chanterelles easily now after all this rain. (They're called Girolles in spring)
Once you start looking, you'll find mushrooms almost all year round and you may not need to grow your own.
If you have a look in my mushroom set in Flickr, just run your
mouse over the photos to get the date when they were found and that will give you an idea of what to look for throughout the seasons.
